Arvicola sapidus
Southern Water Vole resembles Northern Water Vole but is a little larger. It has a somewhat longer tail and a more pointed snout. It can normally be found near running water, but like Northern Water Vole, it is also found inland. The tracks are similar to those of other voles, but are a little larger. Southern Water Voles feed on bark and roots; near water they prefer willows, rushes, and other marsh plants. They will also consume fresh water mussels.
